All 16 remaining members of the President’s Committee on the Arts and the Humanities quit Friday to protest President Trump’s comments about the violence at a white nationalist protest in Virginia.

“Reproach and censure in the strongest possible terms are necessary following your support of the hate groups and terrorists who killed and injured fellow Americans in Charlottesville,” they wrote in a letter of resignation sent to the White House.

“The false equivalencies you push cannot stand. The Administration’s refusal to quickly and unequivocally condemn the cancer of hatred only further emboldens those who wish America ill. We cannot sit idly by, the way that your West Wing advisors have, without speaking out against your words and actions.”

The signers include famed painter Chuck Close, actor Kal Penn, author Jhumpa Lahiri, architect Thom Mayne, and the former head of cultural affairs for New Mexico, Jill Udall, according to the website theartnewspaper.

Other members quit after Trump won the election, and those who quit Friday were all holdovers from the Obama administration.

First lady Melania Trump serves as the honorary chair and other members who are government employees were expected to remain on the panel, which was created during the Reagan administration.

The resignations came after two business advisory panels fell apart and were subsequently disbanded by Trump, who also pulled the plug on his planned infrastructure advisory board.
